HMC724LC3 v03.0514 14 Gbps FA sT RIsE TIME 1:2 FANOUT bUFFER Typical Applications Features The HMc 724Lc 3 is ideal for: inputs Terminated internally to 50 o hms 16 G Fiber Channel d ifferential inputs are d c c oupled RF ATE Applications propagation d elay: 110 ps Broadband Test & Measurement Fast Rise and Fall Times: 19 / 18 ps power d issipation: 300 mW Serial Data Transmission up to 14 Gbps 2 16 Lead c eramic 3x3 mm SMT package: 9 mm Clock Buffering up to 14 GHz Functional Diagram General Description The HMc724Lc 3 is a 1:2 Fanout Buffer designed to support data transmission rates up to 14 gbps, and clock frequencies as high as 14 gHz. All differential inputs and outputs are dc coupled and terminated on chip with 50 o hm resistors to ground. The outputs may be used in either single ended or differential modes, and should be Ac or d c coupled into 50 o hm resistors connected to ground. All differential inputs to the HMc 724Lc 3 are c ML and terminated on-chip with 50 o hms to the positive supply, g Nd, and may be dc or Ac coupled. The differential cMl outputs are source terminated to to 50 ohms and may also be Ac or dc coupled. o utputs can be connected directly to a 50 ohm ground-terminated system or drive devices with cML logic input. The HMc 724Lc 3 operates from a single -3.3 V supply and is available in Ro HS-compliant 3x3 mm SMT package. Electrical specifications, T = +25 C, Vee = -3.3 V A parameter c onditions Min. Typ.
